45 longDescription = ''
46 Zstd, short for Zstandard, is a fast lossless compression algorithm,
47 targeting real-time compression scenarios at zlib-level compression
48 ratio. Zstd can also offer stronger compression ratio at the cost of
49 compression speed. Speed/ratio trade-off is configurable by small
50 increment, to fit different situations. Note however that decompression
51 speed is preserved and remain roughly the same at all settings, a
52 property shared by most LZ compression algorithms, such as zlib.
